To all whom it may concern:

I Be it known that I. LYMAN C. Hurr a citizenof the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in' Apparatus for Removing Carbonaceous Material from Oil Apparatus, of which the following is a specification. M r

This invention relates to improvements in an apparatus for removing carbon material and refers more particularly to the removal of carbonaceous substanes which formed infa relatively solid body inthe expansion or conversion chambers of oil apparatuses.

' Among the important objects of the invention are to provide an apparatus which serves to assist in the breaking up of this carbon body subsequent to the carbon accumulation and thereby facilitate the cleaning Y of the apparatus.

Fig. 1 is a diagrammatic side elevational view of the apparatus connected in a cracking system. Y v

Fig. 2 is a detail of the hoisting mechanism forremoving the chain from the expansion chamber.

Referring to the drawings, heating coil 1 is positioned in the heating chamber of a side fired furnace 2. This coil is connectedby transfer line 3 to the expansion or vaporizing chamber 4. This chamber in turn is connected by a vapor line 5 to a dephlegmator 6 into the upper portion of which the oil charging stock is introduced through the line 7. The vapors rising through the dephlegmator pass off through the line 8and after being condensed in the phlegmation of the vapors in the re uxing o f the carbon body will be broken up into pieces -which can be readily removed from the coil 9 are directed through the'line 10 to the receivin tank 11 where they are collected as liqui distillate. The'raw oil with what reflux condensate it may collect in e dewhich may be opened to permit the accumuhave . mulate and settle upon drawn oil from the lower leg '2' o f lated carbon to be removed from. the chamber.

The chamber is'iurtherequippedwith liquid drawOii lines '15 controlled by valves 16 positioned at different heights on the chamber so that as the level of the carbon rises, and clogs each successive drawoif line, the one above may be utilized to remove the heavy. unvaporized oil constituents from the chamber. When the carbon has accumulated to an amount above the upper residuum drawofl line, the apparatus should-be shut down and the chamber cleaned. In the chamber is positioneda large heavy flexibleelement such as a steel chain or cable 17, of any desired size and of standard construction, the coils being ositioned at the bottom of the. chamber wh' e at intervals throughout its length it is hooked or otherwise tastened by means of members shown at 18, to.

the inner wall of the chamber. By being supported in this manner, it is possible to distribute the flexible element through the carbon body thereby making iteasier to disrupt the carbon after formation. The upper end of the cable is hooked-as shown at 19 to the upper manhole plate 20. i

During operation, the carbon will accuthe lower coils of the chain and as it builds up, the lengths of the cable extending acrom the chamber will be "positioned in the body of the accumulatedcarbon. I

After the apparatus has been shut 'down for cleaning and the carbon sutficiently cooled to be manually remo ved, the upper extremity of the cable is sheave 21 supported by the yoke 22 bolted to the upper flange or manhole plate flange andthe chain pulled vertically from the chamber by means of a winch or other mechanism whereby it will be removed successively from the hooks arranged along the sides ofthe chamber, and with its removal chamber. I 7

It is a very diflicult matter to remove a carbon formation of this character when it is permitted ;to accumulate in a solid form, and where there is an unbroken carbon for mation, considerable time is necessary to remove the carbon from th system.

. By means of the apparatus described, the

passed over the carbon accumulation can be readily broken up and removed from the-chamber, and the system more readily again put into operatlon. t 1

It is becoming necessary to convert the heavier oils such .as fuel oil and other asaccumulates incpnsiderable quantities in a 1 action chamber wherein carbon is precip-itat phaltic base oils which are heavily carbon laden. For this reason'it" is essential that some provision be made .forremovingthe carbonaceous material from the system as it relatively short period of time. I claim as my invention:

, 1. In an apparatus of the character described, the combination of! an enlarged reed and collected during the conversion of oil, of a flexible metal member releasably supported within said'reaction chamber at a pluralityoof. difi'erent vertical points thereing a substantial of and adapted tobe distributed verticauy throughout the. deposited carbon collected Vwhioh is adapted to be filled with precipitated carbon collected during the conversion of oil, of a flexible metal member releasably" supported in said chamber, said element havportion thereof vertically disposed in the portion of such chamber where the carbon collects and adapted to be positioned vertically throughout such carbon to disruptthe same when withdrawn from the'chamber. 7 4 i r 'LYMAN ofIHUFF.
